The rupture of anterior cruciate ligament has been diagnosed by stress test, radiogram and diagnostic arthroscopy, but these methods have several disadvantages of lack of objectivity, exposure to radiation and risk of anesthesia. To eliminate these difficulties, the K-T 1,000 knee ligament arthrometer was used for the objective diagnosis in the injury of anterior cruciate ligament. We performed instrumented measurement of anterior-posterior laxity of the knee in 100 normal subjects by using the K-T 1,000 knee ligament arthrometer under the 15 lb., 20 lb. and maximum anterior pulls, and 20 lb. posterior push. The following results were obtained: 1. The mean anterior displacement at 20 lb.: 4.43mm The mean posterior displacement at 20 lb.: 2.30mm 2. The mean right knee-left knee difference in anterior displacement: 0.89mm 3. The mean anterior compliance index: 1.16mm So, we believed that a right knee-left knee difference and a anterior compliance index are sensitive measures of the integrity of the anterior cruclate ligament. And this test method was helpful for the diagnosis and objective recording in the injury of anterior cruciate ligament. This test method has following advantages: 1. There is no anesthesia risk. 2. The patient and examiner undergo no radiation exposure. 3. Diagnostic arthroscopy may be avoided. 4. Due to patient comfort, there is minimal muscle guarding.

BACKGROUND: There are reviews with regard to the treatment of pigmented nevi present on the palms, soles, and genitalia. One advocated that pigmented nevi on thesa locations should be prophylactically removed to avoid their tuture development into malignant melanoma, while the other believes that this is not practicable. OBJECTIVE: Our purpose was to determine the incidence rates and clinical characteristics and to discuss the management of pigrnented nevi, developed on these areas of the Korean men. METHOD: We examined 1,537 Korean men, between 19 and 21 rears old, to evaluate the pigmented nevi on their palms, soles, and genitalia. RESULTS: Atleast 1 pigmented nevus appeared in 314(20.4%) men on the palms, 189(12.3%) on the soles, and 117(7.6%) on the genitalia. The sizes(mean diameter) of nevi on genitalia, soles, and palms were 4.5mm, 3.1mm, and 2.3mm respectively. The color of the nevi was darkest on the penile shaft(4.3 point) and then glans penis(3.9 points), soles(3.2 points), palms(2.5 points) in decreasing orders of the points. Most of the nevi was consistent with type 1 by Levers clinical classification and their incidence were 357 on palms, 211 on soles, and 128 on genitalia. Among the 21 nevi of type 2, 13 nevi appeared on the soles, and noine of type 3 and type 5 were found. The distribution of the nevi on the palms was of a rather uniform and scattered pattern, whereas, on the soles, they were distinctly concentrated in the midfoot. Tkie nevi on the glans penis appeared larger and more irregular in outline than those on the penile shaft. CONCLUSION: The plantar nevi were larger, darker, and had greater incidence of elevated type compared with the palmar nevi. From this observation, particular attenticn should be paid to the presence of pigmented nevi on the soles.

Hand dermatitis of silk industry workers had been a troublesome problern for a long time. It was said the cause was due to toxic reaction by denatured pupae and physical reaction from high water temperaturc. During Augnst and September 1973, patch test was performed with pupa and cocoon to 680 workers in 4 separate silk factories in order to persue the factors which may cause their hand dermatitis. Among 475 workers who had performed first patch test, only 12 workers in one of four factories showed positive reaction in pupa and we came to know that only that factory had used formalin in order to protect denaturation of pupae and cocoons. Second patch test with pupa and 1% formalin was repeated to 130 subjects including 6 of 12 positive cases in the first pateh test. Five Subjects shosved positive reaction in pupa, also 5 in 1% formalin and 2 of them showed positive reaction in both pupa and 1% formalin. In the second patch test, 3 of 6 who had been positive in pupa at first patch test were positive at pupa. It seemed to be that toxic or allergic theory is not enough to explain clearly the cause of hand dermatitis in silk industry workers. Further stucly is necessarv to elucidate how the silk fiber, water temperature and parasites in the pupa and cocoon contribute to the hand dermmatitis.

Dermstomyositis is a disease mainly of the skin, muscle and blood vessels in which erythematous and edematous changes in the skin are associated with muscle weakneas and inflammation. In adult the disease is commonly associated with underlying malignancy or reticulosis. A 23 year-old male had generalized weakness, intermittent fever, myalgia and purplish red patches on the face. Diagnosis of dermatomyositis was established by clinical manifestations, electromyogram, histologic findings of skin and muscle. He was treated with systemic steroid, with some improvement. Seven months after the onset of dermatomyositis, ecchymoses was noted on the eyelids and forearms. Bone marrow aspiration showed many immature lymphoblasts, characteristic of acute lymphocytic leukemia, He was treated with systemic steroid and vincristine, but no favorable effect was noted. He died of sepsis due to retal abscess on the 34th day in the hospital

Vnrus deformity is a common finding in patients who are candidates for toial knee replacement arthropiasty. To obtain excellent clinical results and to maintain well-aligned and stable prosthetic components in patients who have such a deformity, adequate ligament balancing as well as accurate cone.ction of bony alignment is required. But many technical problems are encountered. Especially the bony defect on the medial aspect of the tibia after adequate bone cutting and ligament imbalance with laxity in the lateral side and contracture in the medial side. Total knee replacement arthroplasty with 43 patients(56 cases) to be mcre than 10 degrees of varus of tibio-femoral angle was done by a single surgeon and reviewed retrospectively. The diagnosis was osteoarthritis in 46 cases, rheumatoid arthritis in 9 cases. The average follow up period was average 33 months(l-7 years). Preoperative varus deformity of average 13.5 degree., was corrected to valgus 6.69 degrees at last follow-up. Postoperative range of motion was 122.5 degree. And the mean knee society score improved from 24.8 to 87.2 postoperatively and the function score improved from 23.6 to 83.9 postoperatively. At self-assements, 88.2% of the patients was very satisfied or somewhat satisfied. Total knee replacement ;u1hroplasty in the patients with vaus deformity is effective procedure to corri.ct deformity and improve clini- c;1 and functional status, but long-term follow up period is required for changing alignment.
